Mississippi Child Support Laws: Guidelines and Calculations

How Mississippi Child Support Works

Mississippi child support laws are governed primarily by Mississippi Code sections 43-19-101 through 43-19-105, which establish the guidelines courts use to calculate and enforce support obligations. The Mississippi Department of Human Services (MDHS) Division of Child Support Enforcement administers the state's child support program.

Mississippi is one of a small number of states that uses the Percentage of Income Method to calculate child support. Under this approach, only the non-custodial parent's income is considered when determining the support amount. The custodial parent's income does not factor into the basic calculation, although the court may consider it when deciding whether to deviate from the guidelines.

The state's guidelines carry a rebuttable presumption that they are correct. This means the calculated amount is presumed to be the right amount unless a parent presents evidence that applying the guidelines would be unjust or inappropriate in a particular case.

Establishing Paternity in Mississippi

Before a court can order child support, legal paternity must be established for children born outside of marriage. Mississippi law provides several ways to establish paternity.

Voluntary Acknowledgment

The simplest method is for the father to sign an Acknowledgment of Paternity form at the hospital after the child is born. This form has the same legal effect as a court order once filed with the Mississippi State Department of Health.

Court-Ordered Paternity

If the alleged father refuses to acknowledge paternity voluntarily, the mother or MDHS can file a paternity action in court. The court may order genetic testing, which typically involves a simple cheek swab. If testing confirms paternity, the court will enter an order establishing the legal father-child relationship.

Benefits of Establishing Paternity

Establishing paternity provides important benefits for the child, including:

• Legal access to both parents' health insurance, disability, and death benefits
• The right to receive financial support from both parents
• Access to the father's family medical history
• Eligibility for Social Security survivor benefits
• Inheritance rights

How to Apply for Child Support in Mississippi

Parents who need help establishing, enforcing, or modifying a child support order can apply for services through MDHS. Here is what you need to do.

Contact the Division of Child Support Enforcement at 601-359-4861 or visit the MDHS online portal. You can also download the application and mail it to the Department of Human Services with the $25 service fee.

Required Documents

When applying, gather the following documents:

• Valid government-issued identification

The $25 application fee is waived for parents receiving SNAP, Medicaid, or TANF benefits.

How Is Child Support Calculated in Mississippi?

Mississippi uses the Percentage of Income Method under Mississippi Code section 43-19-101. This method applies a fixed percentage to the non-custodial parent's adjusted gross income based on the number of children who need support.

Step 1: Determine Gross Income

The court first calculates the non-custodial parent's gross income from all sources. Under the statute, gross income includes:

• Wages, salaries, and tips
• Self-employment income
• Commissions and bonuses
• Interest and dividend income
• Pension and retirement income
• Social Security benefits
• Disability benefits
• Workers' compensation
• Unemployment benefits
• Rental income
• Trust income
• Alimony received from another relationship

Step 2: Calculate Adjusted Gross Income

The court subtracts allowable deductions from gross income to arrive at the adjusted gross income (AGI). Permitted deductions include:

• Federal, state, and local income taxes
• Social Security (FICA) contributions
• Mandatory retirement contributions
• Support payments already being made for other children under a prior court order

Step 3: Apply the Percentage

The monthly adjusted gross income is multiplied by the appropriate percentage from the following table.

Number of Children	Percentage of Adjusted Gross Income
1 child	14%
2 children	20%
3 children	22%
4 children	24%
5 or more children	26%

For example, if a non-custodial parent has an adjusted gross income of $4,000 per month and has two children, the presumptive child support obligation would be $800 per month (20% of $4,000).

Factors That May Adjust the Amount

The court may deviate from the guideline amount based on the "best interests of the child" when the standard calculation would be unjust or inappropriate. Under section 43-19-101(4), factors that may justify a deviation include:

• Extraordinary medical, psychological, educational, or dental expenses
• Seasonal variations in a parent's income or expenses
• The age of the child and related costs
• Special needs of the child or either parent
• The combined assets and incomes of both parents
• Child care costs necessary for employment or education
• Any other relevant facts the court finds important

When a court deviates from the guidelines, it must state the reasons on the record or in the written judgment.

Medical Support Requirements

Under Mississippi law, all child support orders must include provisions for reasonable medical support. The court determines which parent should provide health insurance coverage for the children.

If employer-sponsored health insurance is available at a reasonable cost, the court will typically order one or both parents to maintain coverage. Under Mississippi Code section 43-13-303, employers must enroll eligible children in available health plans when ordered and must withhold any required employee contributions for that coverage.

If health insurance is not available at a reasonable cost, the court must make specific findings about the unavailability and establish a method for dividing uninsured medical expenses between the parents.

How to Modify Child Support in Mississippi

Mississippi law recognizes that financial circumstances change over time. Parents can seek a modification of an existing child support order through two pathways.

Three-Year Review Cycle

Under Mississippi Code section 43-19-34, MDHS notifies both parents every three years of their right to request a review of the current child support order. When a parent requests a review, MDHS evaluates whether the existing order differs significantly from what the current guidelines would produce.

No proof of a material change in circumstances is required for these three-year reviews. If the review shows the order should be adjusted, MDHS can seek a modification.

Modification Outside the Three-Year Cycle

Parents who need a change before the three-year mark must demonstrate a material change in circumstances. Courts have recognized the following as qualifying changes:

• A significant increase or decrease in either parent's income (generally 25% or more)
• Job loss, disability, or involuntary reduction in income
• Changes in the custody arrangement
• Significant new medical expenses
• Additional children to support from a new relationship
• Incarceration of the paying parent

Important Rules About Retroactivity

Under section 43-19-34, a downward modification cannot be applied retroactively. If you lose your job, the original support amount continues to accrue until the court enters a new order. An upward modification, however, may be ordered retroactively back to the date of the event justifying the increase.

This is why it is critical to file for modification as soon as circumstances change rather than waiting and allowing arrears to accumulate.

Enforcement and Penalties for Non-Payment

The MDHS Division of Child Support Enforcement has broad authority to collect unpaid child support. Mississippi uses a combination of administrative and judicial enforcement tools.

Administrative Enforcement Actions

• Income withholding: All child support orders include an automatic income withholding provision. Employers must deduct the support amount from the paying parent's wages and send it to the Mississippi State Disbursement Unit.
• Tax refund interception: Federal and state tax refunds may be intercepted and applied to past-due support.
• License suspension: Driver's licenses, professional licenses, and recreational licenses may be suspended for non-payment.
• Passport denial: Under federal law, passports are denied, restricted, or revoked when arrears exceed $2,500.
• Credit bureau reporting: Delinquent child support is reported to major credit bureaus, affecting the parent's credit score and ability to obtain loans.
• Property liens: Liens may be placed against real and personal property to secure unpaid support.
• Financial account seizure: Bank accounts and other financial assets may be frozen and seized.

Contempt of Court

When administrative actions are insufficient, the custodial parent or MDHS can file a motion for contempt. The non-paying parent must appear in court and "show cause" for the failure to pay. If the court finds willful non-payment, penalties include jail time of up to six months per contempt finding, fines, and mandatory payment plans.

A parent who can demonstrate a legitimate inability to pay (such as a documented medical condition preventing work) may avoid contempt sanctions, but the court will likely order a modification hearing.

Criminal Penalties Under Mississippi Code 97-5-3

Mississippi treats willful failure to support a child as a felony under Mississippi Code section 97-5-3. In 2023, the legislature amended this statute (SB 2634, effective July 1, 2023) to extend the criminal obligation from age 18 to age 21, aligning it with the civil child support obligation.

First offense penalties:

• Fine of $100 to $500
• Up to five years with the Mississippi Department of Corrections
• Or both

Second or subsequent offense penalties:

• Fine of $1,000 to $10,000
• Two to five years with the Mississippi Department of Corrections
• Or both

Defenses to prosecution include proof that the parent was unable to provide support due to physical incapacity or other good cause shown to the court.

When Does Child Support End in Mississippi?

Mississippi has one of the highest age thresholds for child support in the country. Under Mississippi Code section 93-11-65, child support continues until the child turns 21 years old, not 18 as in most states.

Events That Trigger Early Termination

Child support may end before the child turns 21 if any of the following occurs:

• The child becomes emancipated by court order
• The child gets married
• The child enlists in the military
• The child is adopted by another person
• The child voluntarily leaves the custodial parent's home, establishes independent living, and obtains full-time employment while discontinuing educational pursuits

Emancipation in Mississippi

Under section 93-11-65, a child may be considered emancipated if the child has reached age 18 and discontinues full-time enrollment in school (unless the child has a disability), or if the child voluntarily moves out, establishes independent living, and works full-time while no longer attending school before reaching age 21.

A parent seeking to end support based on emancipation must file a petition with the court. The existing support order remains in effect until the court enters a new order.

Support for Disabled Adult Children

If a child has a physical or mental disability that prevents self-support, the court may order child support to continue past age 21. The 2023 MDHS Quadrennial Review of child support guidelines recommended strengthening this provision, with the noncustodial parent bearing the burden of proving the disabled adult child is capable of self-support.

Arrears Survive Emancipation

It is important to understand that emancipation or reaching age 21 does not erase past-due child support. Under section 93-11-65, any arrearage that exists at the date of emancipation must still be paid in full. The statute of limitations for collecting child support arrears extends to seven years past the age of majority, meaning enforcement actions can continue until the child turns 28.

Interstate Child Support Enforcement

When parents live in different states, Mississippi participates in the Uniform Interstate Family Support Act (UIFSA), which provides a framework for establishing, enforcing, and modifying child support orders across state lines.

If the non-custodial parent moves to another state, MDHS can work with that state's child support agency to enforce the Mississippi order. Income withholding orders can be sent directly to out-of-state employers, and enforcement remedies such as tax intercept and license suspension remain available regardless of the parent's location.
